“…The heterogeneity of our samplings, along geographical, age-related, and avian gender, could be determinants for the observed differences (see Bush, 1990 ). Likewise, the richness of helminth species in some of these studies [21 in Padilla-Aguilar et al (2018) , 25 in Farias and Canaris (1986) , and 20 in Martínez-Haro et al, 2012 )] is similar to our findings (23). These richness values are in accordance with the Fedynich and Pence (1994) statement, who pointed out that the taxonomic composition and infections of individual hosts are determined by the seasonality of the samples, as well as by the vagility of the birds, which promote the exchange of helminths along their migratory route.…”

“…Taxonomic composition of helminth fauna of Mexican waterfowl does not seem to follow a structured pattern; in our study, nematodes and trematodes were the best represented groups of helminths among anatids, with eleven and six species, respectively. Similar findings were reported by Padilla-Aguilar et al (2018) (eight nematodes and seven trematodes) in the Altangatepec wetlands, in Central Mexico; on the contrary, Martinez-Haro et al (2012) registered nine trematodes and eight cestodes in the Lerma marshes, also in Central Mexico. On the other hand, studies conducted in Northern Mexico revealed a higher presence of platyhelminths.…”

“…From a taxonomic perspective, this study increased the knowledge of the inventory of helminths associated to Mexican birds; this group of hosts has been neglected in Mexico, since only ≈12.2% of the birds distributed in the country have been studied ( Pérez-Ponce de León et al, 2011 ). As a result of our research, the nematode Capillaria contorta and the acanthocephalan Filicollis sp., are registered for the first time in Mexico and another 11 taxa for the marshes of Lerma and central Mexico (see Pérez-Ponce de León et al, 2007 ; Mercado-Reyes et al, 2010 ; Martínez-Haro et al, 2012 ; García-Varela et al, 2013 ; Padilla-Aguilar et al, 2018 ). In addition, 69 new host records for the sampled waterfowl were reported ( Table 1 ).…”

Gastrointestinal helminths of migratory waterfowl can cause several lesions that may affect the health and even the survival of their hosts. As part of an ongoing project that aims to inventory the helminth species that infect this group of birds, as well as the histopathologic lesion they cause, a total of 200 digestive tracts of nine species of anatid birds ( Spatula discors, S. cyanoptera, S. clypeata, Mareca strepera, M. americana, Anas crecca, A. acuta, A. platyrhynchos diazi, and Oxyura jamaicensis ) were collected in the Atarasquillo marsh of Lerma, in the State of Mexico. The present work had a twofold goal: to determine the taxonomic identity of the helminth species present in waterfowl as well as their infection levels and to describe the lesions caused by gastrointestinal parasites in migratory and resident anatids in Atarasquillo marsh, State of Mexico. The specimens were examined using routine helminthological and histopathological techniques. A total of 23 helminths were identified: six trematodes ( Zygocotyle lunata, Notocotylus triserialis, Notocotylus seineti , Psilochasmus oxyurus, Australapatemon burti and Cotylurus magniacetabulus ), four cestodes ( Cloacotaenia megalops, Fimbriaria fasciolaris, Gatrotaenia cygni and Diorchis sp.), eleven nematodes ( Echinuria uncinata, Tetrameres sp., Tetrameres fissispina, Hystrichis sp ., Streptocara sp., Amidostomum sp., Epomidiostomum uncinatum, Capillaria sp., Capillaria contorta, Ascaridia sp. and Heterakis sp.) and two acanthocephalans ( Pseudocorynosoma constrictum and Filicollis sp.). At the proventriculus level, Echinuria uncinata caused the most severe lesions; in the gizzard, Amidostomum sp. and E. uncinatum produced hemorrhages and necrosis. Finally, the main lesions found in the intestine (necrosis, heterophilic granulomas and the formation of lumps on the serosa) were caused by the implantation of the acanthocephalans’ proboscis. Eleven species of gastrointestinal helminths found are new records for the Lerma marshes, as well as the first record in Mexico of the nematode Capillaria contorta and the acanthocephalan Filicollis sp.

“…In particular, the knowledge of nematodes from anatids in South America is very scarce. Most investigations have been carried out in Chile, Mexico (González et al, 2005; Mercado Reyes et al, 2010; Martínez Haro et al, 2012) and Brazil (Vicente et al, 1996; Vianna Mohr, 2001), while information about Argentina is still lacking (da Silveira et al, 2006; Agüero & Diaz, 2013).…”

Stomach nematodes of three sympatric species of anatid birds off the coast of Patagonia

et al. 2015

The present study focuses on the nematode community in the stomachs of three sympatric anatid bird species from the Central Patagonian coast, Argentina. The bird species include the Chubut steamer duck, Tachyeres leucocephalus, the crested duck, Lophonetta specularioides, and the black-necked swan, Cygnus melancoryphus. Up to 138 nematodes representing five species were recovered from 10 of the 13 ducks examined, with an overall prevalence of 77% and a mean intensity of 13.8. Nematodes isolated from the gizzard were Streptocara formosensis and Sciadiocara legendrei (Acuariidae) in T. leucocephalus, and Epomidiostomum vogelsangi (Amidostomatidae) in C. melancoryphus, whereas Echinuria uncinata (Acuariidae) and Tetrameres (Petrowimeres) fissispina (Tetrameriidae) were found in the proventiculus of L. specularioides. In particular, S. legendrei was registered for the first time in South America and T. leucocephalus, whereas T. fissispina represents a new record in Argentina and L. specularioides. Moreover, E. vogelsangi and E. uncinata were isolated in Patagonia for the first time. The birds studied herein are sympatric in their distribution, and two of them are syntopic breeders; however, they were infected with different parasite species. This situation could be partially due to their diet or their seasonal movements, or a combination of both. Despite the low number of hosts examined, this work enhances our knowledge about parasites from a frequently occurring group of birds on the Patagonian coast, a subject that has not been studied extensively in South America.

“…and Sobolevicanthus gracilis Zeder, 1803 have been recorded in C. atratus, C. buccinator, C. cygnus, and C. olor from Asia, Europe, and North America (MCDONALD, 1969;BLUS et al, 1989;ZUCHOWSKA, 1997). In the neotropics there are few findings, with a report in waterfowl from Mexico: Sobolevicanthus krabella Hughes, 1940 and S. gracilis;(FARIAS & CANARIS, 1986;MARTÍNEZ-HARO et al, 2012). For the black-necked swan, Pfeiffer (1960) isolated R. bulbocirrosus from captive birds in Austria; nevertheless, the author specified that the birds died soon after their arrival from Argentina.…”

Black-necked swans are distributed across South America and face conservation problems in Chile according to data of the State institution SAG. The aim of this study was to identify helminths and to assess associated tissue damage via histopathology. A total of 19,291 parasites were isolated from 21 examined birds; 17 species were identified, including nematodes, flukes, and tapeworms. Of these, 12 were new host records, 13 were reported for the first time in Chile, and 5 were new records for the Neotropical region. Further, the flukes Schistosomatidae gen. sp. and Echinostoma echinatum are of zoonotic concern. Regarding histopathology, an inflammatory response was found along the birds’ entire digestive tract. Nevertheless, it is difficult to declare that there is a clear association between such lesions and isolated parasites, as other noxa could be responsible as well. Although in some cases there was an evident association, such inflammatory responses and necrosis were minimal, as occurred with Capillaria, Retinometra, Catatropis, Echinostoma, and Schistosomatidae gen. sp. Nevertheless, Epomidiostomum vogelsangi caused granulomatous injuries, an important inflammatory response, and necrosis, but it always circumscribed to superficial layers of the gizzard. Conversely, Paramonostomum was not associated with an inflammatory response despite a high parasitic load.
